Well if the business name is Special Ops Tactical they surely know wtf they're doing.
Hope you've got a can. |

I would be pretty leery.
That's not very much dwell time, plus it's lower pressure than carbine or mid. Nick |

I would love to know the gas port size. Probably .125.
I'm working on a 16" ish rifle length upper right now. Will be run with a suppressor though. |

I wonder if that gas block seat is long enough to run a standard front sight base. I guess it probably doesn't matter if the gas block is long enough, since I don't know if anyone can drill a nitride barrel for taper pins.

From what I've gathered the company started from former Spikes employees. I actually met the owner and his wife and at a gun show a little over a year ago, I bought a 10in rail from them. Nice people and seemed like straight shooters. I want to build a rifle with this barrel but I have other budgetary obligations that are more important right now.

I have dealt with the owner Garrett when he worked at Spikes many times. Pretty good guy I did not know he started his own place but good on him.

I decided against the pin and weld and bought the 16" instead. I should have it Friday.

They sure do have a lot of what looks exactly like Ballistic Advantage Hanson Profile barrels. Right down to the NiB barrel extension.

Kinda similar to what MicroMOA was doing before they closed down. Has the same angled port. I have one of their rifle-length gas system 16" barrels, and am happy with it. I had to open the port to .073" (IIRC) to get it to function reliably, but it's just a game-gun, and I expected to have to mess with it a little bit. I would have bought another one, had they not gone out of business.

I have a feeling I know why your rear sight is so far forward. But I would think they're hard to use that far forward.... Maybe not. I know they kind of get in the way of manipulating the CH when they are folded down all the way back . Sort of. Part of the downsides of them.
Cool build let us know how she shoots. I can't remember if you posted it earlier, do you know what size your gas port is? .093 was it? |

I’d like to hear how it shoots. Been kicking around the idea of building an upper with the 14.8 or 16.1.
Thanks |

I just got back from the range and I'm impressed with how the gun felt.
I ran 120 rounds of IMI and PMC X-Tac M855 ammo through it with no failures. The outside temp right now is 62 degrees. It was great to shoot. I can really tell the difference between it and my midlength 556. All milspec parts were used. Parts list: Anderson MFG.

Very nice. I bet that is a super nice shooter!!! I remember a few people that have done 605's had said they are one of their favorite rifles and have a lot of fans when they let people shoot it. If I ever do a Vietnam era build, that's what I'd like to do. Although I'd probably do like you and just do 16" and not do the exact length they used to avoid attaching the muzzle device permanently.

Damn this place costs me money.
I picked up one of their 16.1" rifle length gas system barrels. I ordered it Tuesday, and it I just got the delivery notification a few minutes ago--that's pretty damn fast! So fast that I don't have the rest of the parts I need for the build, so it may be a few weeks before I get it to the range. I am skeptical of any business named things like "Special Ops Tactical," but I'm willing to give them a shot. I'll post some feedback after I get it built. |

I received my 9.2" today.
A 1/16 drill bit fits snugly in the gas port, a 5/64 will not go in at all. |

A #48 drill bit, which is .076", fits perfectly in the port. This makes me confident that it will work properly, as that is the exact same size I had to open up the gas port on my MicroMOA 16"/rifle gas barrel to make it work. The barrel itself looks very well made, with an attractive finish and nice laser etching. I'm hoping it is accurate. |

I emailed Garrett Potter a while back about these barrels. He said these were designed to run with a milspec carrier, a standard buffer spring, and an H1 buffer, although he said he would not go heavier. There is not enough bearing surface for a FSP, so they won't work for a traditional dissipator build. From the looks and sounds of it, they should make a reliable soft shooting rifle. The 14.8 is pretty interesting and I'm curious as to exactly how much handguard you need to cover your gas block but not obstruct the muzzle device in any way.

I bought a 16" mid SOT from AIM several years ago and it has performed flawlessly with good fit/finish. I had heard good things about Garrett and figured I'd try one out.
It lives in my mom's closet now as her primary hd and I have as much faith in it as any other AR I've got. I had her shoot the Mossberg 500 12ga that I had given her for that purpose and let's just say that wasn't working out. She tried the AR and could easily stay on target and manipulate all controls. |

Same here with the 9.2". I got a M.I. 7" handguard and it covers about 3/4 of the gas block. I was talking to Garrett about some different options but he hasn't got back to me in a couple of days so I went with a BCM 8". If the guard is actually 8" it should be fine. Any more and I'll be cutting it close. View Quote |

Thanks for the update! I might just grab one of those barrels.

Finally finished the 9.2" upper. It's replacing my PSA 10.5". I was having a hard time finding the right handguard because of the gas block position on the barrel. I wanted the handguard to cover the gas block but leave the threads exposed for my silencer. I went with a BCM Alpha 8". A 7" was too short, and I didn't want to have to cut down the 9"
It still leaves a little bit of the gas block exposed, but it's close enough. Attached File It weighs a hair under 7 pounds without a mag. Attached File I'm happy with how it turned out so far and I can't wait to shoot it. |

Doesn't a 605 have a 15" barrel, rifle gas? I believe they were made so they could mount a suppressor, so I'm sure they got some back pressure there. But I think they work without the suppressor on too. http://photos.imageevent.com/willyp/firearmsalbums/uscoltarmalitem16ar15556/coltmodel605/605%20parts%20set.jpg https://bpullignwolnet.dotster.com/retroblackrifle/sitebuilder/images/605-22-713x401.jpg https://bpullignwolnet.dotster.com/retroblackrifle/sitebuilder/images/601_605_Field-600x416.jpg https://66.media.tumblr.com/6e30993f20357a7a642f3350a1ff9087/tumblr_mzcmncNMfA1qivon6o1_1280.jpg View Quote A big negative. The one with a suppressor is not a 605 it is a 603.
